Daniel Burke, 51, of Nashua pleaded guilty Wednesday to negligent homicide and abuse of a corpse. He admitted to killing 52-year-old Christina Hill on July 4.

The Nashua Telegraph reports prosecutors described a grisly scene in which police found the badly decomposed body wrapped in a blanket and a plastic sheet on July 20. A building manager discovered the body after entering the apartment to investigate a smell.

Burke told police he pushed Hill during an argument and she hit her head on a cabinet and slumped to the floor.
